Serious security flaws that could give attackers complete access to a phone's data have been found in software used on tens of millions of Android devices.
The bugs were uncovered by Checkpoint researchers looking at software running on chipsets made by US firm Qualcomm.
Qualcomm processors are found in about 900 million Android phones, the company said.
However, there is no evidence of the vulnerabilities currently being used in attacks by cyberthieves.
"I'm pretty sure you will see these vulnerabilities being used in the next three to four months," said Michael Shaulov, head of mobility product management at Checkpoint.
"It's always a race as to who finds the bug first, whether it's the good guys or the bad."
